To all whom t5 may concern Be it known that I, GEORGE H. Loner, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of'Ohio, have invented a certain new and useful Automobile-Radiator; and I do hereby declare the following to be a full, clear, and exact description Oi the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to automobile radistore and it has for its object to provide an efiicient radiator that may be formed at a low cost and wherein the parts maybe readily separated for purposes of repair, and one wherein the deleterious efiects of freezing will be entirely obviated. '4

The invention particularly has for its object to ,provide a radiator wherein not only wateffrom the engine will be kept at a low temperature, but also to provide a radiator wherein, the water passageways are so formed that they will expand if the water freezes and thus prevent the ice from ripping the seams. It also has for its object to provide a means for yieldingly resisting the expansion and causing the water passage-ways to return to their normal sizes or positions when the ice has melted. It also has for its object to provide a radiator wherein water passage-ways are formed of strips having the same form and configuration and may be assembled to form not only the water passage-ways, but also air passage-ways. it also ha for its object to not only form .s strips or the same form and configure but also to so forn them that the Will be deflected in its movement through i radiator While cooling the water. ine invention also has for its object the production of other features and advantages that will appear from the following' description.

The invention may be contained in radiators of different forms. I have selected one of such constructions as an example and shall describe it hereinafter. The construction. selected is illustrated in the accompanyin drawings.

*iigure l of the drawings is a front view of t is radiator containing my invention,

Fig. 2 is a front View of a portion of the core of the radiator. Fig- 3 is practically a full 1, Fig. l, is the radiator containiirmy invention having the usual water boxes in the upper and lower parts of the radiator body. 2 is the core'of the radiator which is formed of a plurality of vertical strips that extend from the upper to the lower water boxes of the radiator 1. The strips are corrugated longitudinal and so as to form semicylindrical corrugated parts 3 separated by flat parts 4:. The strips are also provided with corrugated edges 5 that zigza back and forth along the front and rear e ges of the strips. The strips being formed alike, they may be readily formed by running long strips from acoil between rollers that will form the longitudinal and edge corrugations and then the strips may be cut to the desired length. I

Two sets of strips are used in the formation of the core of the radiator. The strips of one set are arranged in airs and are placed face to face so that he semi-cylindrical parts of the longitudinal corrug tions will form tubular passage-ways err-'- tending between the pairs of strips, the tubular passage-ways being; separated by the fiat portions of the longitudinal corruga tions which in each pair abut one another. The zigzag or angular corrugations of the edges of the pairs of strips fit into one another so to form closed seams at opposite edges of each pair of strips. The upper ends 6 of the pair of strips are turned over so as to extend at right angles to the tubular passageways that are thus formed. The ends 6 are at sufficient length. so that they will overlap the corresponding ends of successiye pairs. When the edges of the strips are dipped in solder, the edges 5aresealed.

The ends of: the strips are also dipped in solder and consequently are sealed. When the strips are placed side by side and mounted'to form the core of the radiator, the

water passes through the tubular passageways 11 that are formedbetween the pairs of the strips. The strips being corrugated longitudinally, when the Water freezes in the passage-ways, Will have ample room for expansion. or bellying outward withoutpulling on the soldered and sealed edges. This prevents ripping along the corrugated edges.-

loo

vided with a strip 7 of elastic material which is transversely corrugated to form conipara.

tively'long spreading pressure parts. The corrugations have flat contact portions 1?}:

which press againstthe pairsof strips, that" are placed together to, form; the' Water pitssage-ways. The flat contact portions 1'4 slidaloly move along the pairs of strips when the'ipairsol" strips are placed together or When tile alls of the pairs of strips expand by reason ofthe freezing of the'water.

Each strip? is soldered at its center 8 to one ofeach pair of strips. When the pairs of strips are placed together to form the core of the radiator, they are forced together so as to compress the parts of the elastic stri- 7. The strips 7 by their pressure agamst the walls of the pairs of strips 9 and 10 operate to yieldingly maintain the abutting flat portions & in contact. When, however, the Water freezes the expansion of the ice causes the Water passage-Ways to open and consequently forcethe center portion of the strips 9 and l0'apa'rt against the resistance ofthe spring parts formed in the elastic strip 7.

In order that the strips may he held in spaced relation. and to give roomfor the corrugations of the elastic strips 7 I have provided a second set of strip 19, formed in. the same as to longitudl al and edge corrugations as the strips of the first set de-.

scribed above. The second set of strips is provided with large openings 15 through which the corrugation. of the strips 7 may extend. The edges of each strip of the second set are so placed that the corners abut the corners of the ct gcs of the pairs of strips of the other set. Thisnot only spaces the i s of strips and 10, but also gives the -co1nhed appearance to the front and r of the radiator. Tile lormitudinal corrms of the strips causes the air passing ugh the openings formed by the abuted es 5 to he deflected hack and forth s through the radiator-to cool the i strips having the water passage By this arrangement, the ai r is ht into intimate contact with the Walls water passageways and rapidly cools ses through the radiator.

they maybe hound,together and the edges dipped in solder. likewise, the ends of the core may he dipped in the solder so as to seal the overlapp ng ends of the pairs oi the strips that form the Water passac'cwvays.
